Abstract

Through the analysis on the cases of the transmission line gallop over the years, the meteorological condition and the geographical location have a dramatic effect on the gallop phenomenon. And the conductor gallop can be evaluated by the thresholds of the weather factors and the degree of the terrain fluctuation. In this paper, an early-warning method for the conductor gallop on the transmission line is presented. Based on the real-time small grid weather forecast data and the geographical information, the potential gallop region can be found 3 days in advance. Applying this method, an early-warning system for the conductor gallop on the transmission line has been developed in Hubei, China. Since it was put into operation, the system has accurately predicted the gallop region and intensity many times. The practical application shows that the early-warning method has high accuracy and good practicality. Furthermore, it is helpful to develop the other early-warning systems on the transmission line, such as the icing, lighting early-warning systems.
